I'm adding a lot more test cases like this to APFloat's unittests so hopefully we won't have any other bugs lying around.

Hi, We need to generate "Floating point constants" in our code. In http://llvm.org/docs/LangRef.html it is explained that FP has to follow special encoding rules to be handled by LLVM later one (hexadecimal coding...) Is there any code available in LLVM to handle this kind of "standard float to LLVM float" conversion? Thanks. Stéphane Letz

Hi, after upgrading to 2.1 I noticed that the format for floating point numbers in .ll files apparently changed. I now get errors like "llvm-as: var.ll:48,0: Floating point constant invalid for type" for such code: "@gmFloat = constant float 0.3". I checked with llvm-gcc and it now generates code for the hexadecimal floating point representation. The documentation at

Hi, do you know, a method to convert an decimal value (integer) to the corresponding hexadecimal value ? thinks for help.

It appears to me based on my experiments with llvm-as that literal floating-point constants may be specified in the 64-bit IEEE hexadecimal format, but not in the 32-bit format. For instance, this file: target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32- i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64- f80:128:128" target triple =

>From the language guide: "The one non-intuitive notation for constants is the optional hexadecimal form of floating point constants. For example, the form 'double 0x432ff973cafa8000' is equivalent to (but harder to read than) 'double 4.5e+15'. The only time hexadecimal floating point constants are required (and the only time that they are generated by the disassembler) is

Certainly looks like one; I've cc'd this to the bug list (but won't be able to look into fixing it). Duncan Murdoch > > >> sessionInfo() > R

Hi all, I have noticed incorrect parsing of very small hexadecimal numbers like "0x1.00000000d0000p-987". Such a hexadecimal representation can can be produced by sprintf() using the %a flag. The return value is incorrectly reported as 0 when coercing these numbers to double using as.double()/as.numeric(), as illustrated in the three examples below:

hi folks, this is driving me up the wall. Apologies for posting twice in the same week, I'm writing up a thesis. I wish to color-code some dots in an xy plot. I've got a csv file with various elements, one of which is the color-key (with the header 'color'). If the color-key is decimal (eg. 1,2,3) then I can use plot (X ~ Y, col=data$color) The problem, however, is that using

From: Brett Walker <brett.walker at geometry.com.au> When printing hexadecimal numbers to a fixed width, padded with leading zeros, and also having a leading '0x'; the resultant string can be shortened by up to two characters if any leading zero padding character required is. int hexnum = 0x00001234; printf("%08X", hexnum); // results in 00001234

In short if suppose i have some expression as a=b+c-d*e, and with the help of LLVM pass i want to make a string like this:- "[Hexadecimal address of 'b'] [opcode of +] [Hexadecimal address of 'c'] [opcode of -] [Hexadecimal address of 'd'] [opcode of *] [Hexadecimal address of 'e']". Than how can i make it................ -- View this message in

Hi there, could somebody help me to convert a decimal number into a hexadecimal number? I know that there is the function "sprintf", but the numbers I want to convert consist of 20 or more numbers. "Spintf" is not able to convert these big numbers. Thanks for any help. Antje [[alternative HTML version deleted]]

Hi list, I''m new to this list, I just subscribed because I have some ackward about IPRoute2. First, while playing with NetFilter'' "MARK" target, I met a weird behaviour once I tried to use this marks in the RPDB : the packets where successfully marked, but it seemed that RPDB didn''t succed in matching them (for those who already know the answer, I only used

Hi Dieter, Sorry my mistake. I wanted to convert them into Decimal (not Hexadecimal).

Hi, The -dot-cfg option of opt will write a diagram of an analyzed function's CFG to DOT format. If you then open the DOT file, you will see that the BasicBlocks are uniquely identified with hexadecimal addresses. For example, an edge from one block to another may look like: Node0x10026b0:s0 -> Node0x1004c20; I've been trying to figure out where these hexadecimal addresses
